Charge controller for multi-cell Li-Ion packs
The ADP3810AR-12.6 is a battery charge controller IC from Analog Devices designed for 1 to 4 series Lithium Ion or Polymer cells, targeting a nominal pack voltage of 12.6 V. It provides constant-current charging that is programmable via an external resistor, with a maximum charge current of 6 mA — suited for low-rate topping or maintenance charging rather than high-current bulk charging. Integrated fault protection covers over-current and over-voltage conditions, which helps safeguard the cell stack during charge termination or a fault event.
Package and board-fit for the BOM
The supply voltage range extends to 16 V maximum, which provides headroom above the 12.6 V pack target for the charge control loop.
Lifecycle and compliance snapshot
Supplied in Bulk packaging (tube or tray), not tape-and-reel — factor this into your pick-and-place feeder setup or order a reeled variant if available.
